Smallest internal combustion engines in the world

Smallest internal combustion engines in the world by Günter Bettinger

These are the smallest internal combustion engines in the world
They were made by Günter Bettinger

He tried to give the machines an individual look that visually distinguishes them from the otherwise known types. For this he sometimes neglects the ideals of thermodynamics in favor of my design ideas.
